Dont know if this has been brought up but the J201 is an great replacement for the 2sk30A-O (VCO). The pinout is different D S G vs D G S, but I have one in mine right now and I cant tell a difference..

165 and 166 are both PISO shift registers but have a completely different pinouts. I have no idea what the third part is. Compatible parts will usually be the same type of logic chip made by different manufactures so SN74HC165N, M74HC165B1R, etc are the all interchangable (74HC165 being the key thing). There are of course exceptions but that is a general guideline to follow

It's before willzyx had the complete kits, so I got them from Mouser because they said they would be compatible. :lol: They didn't have the 74HC165's in stock. Also, I have no idea why I have the extra ICs.

@textile, I've been meaning to thank you for finding these. I have them installed in a couple projects now, and I'm very pleased with them. Also, at 3 for $1, you can't beat the price!

Also, everyone, I can confirm that 2SC2259 is a viable alternative to 2SC1583. I've tested one in the VCO of my experimental x0x build, and the traces off the VCO on my oscilloscope were indistinguishable. I have yet to test in the filter, where it may actually change things a bit, as the C2259 basically IS a C1583, but with a much wider and higher range of Hfe values.

As I understand I could replace the 2sk1583 with 2 mached transistors?If yes.. which ones?

2SC1583 = dual NPN, 2sk1583 = Mosfet i.e., the wrong type.
